HVAC Maintenance

Listed below is a general guideline on what our technicians do during a RCM Precision Tune Up. The exact operation depends on the type and age of equipment being serviced. This procedure covers most applications and we sometimes charge extra for excessively dirty equipment.

Furnace Precision Tune Up

	Check thermostat
	Start system to verify operation
	Thoroughly clean interior and exterior of furnace with vacuum
	Wash burners and wipe down cabinet
	Check air flow
	Inspect all sensors and devices
	Clean Flame Sensor
	Inspect flue and diverter
	Inspect heat exchanger with video camera for cracks, rust and heat stress
	Perform complete electrical analysis on all associated motors, sensors and devices. Includes necessary resistance, current draw and voltage drop
	Adjust gas pressure, burners, pilot, blower speed
	Perform carbon monoxide tests if necessary
	Measure temperature rise
	Record equipment model & serial numbers and all IAQ equipment
	We record all findings/specifications for necessary future reference

Air Conditioning Precision Tune Up

	Check thermostat
	Start system to verify operation
	Shut down humidifier for season
	Thoroughly clean interior and exterior of condenser with garden hose
	Check air flow at condenser and evaporator
	Inspect all associated sensors and devices
	Measure refrigerant level/pressure and temperatures
	Perform complete electrical analysis on all associated motors, sensors and devices. Includes necessary resistance, current draw and voltage drop measurements.
	Perform compressor strength test
	Adjust refrigerant level (Extra Charge)
	Measure temperature drop
	Record equipment model & serial numbers and all IAQ equipment

We record all findings/specifications for future reference should the necessity arise. It is strongly recommended that HVAC equipment be maintained yearly.
